System and method for neutron and gamma radiation detection using non-homogeneous material scintillator

Patent Brodsky, Jason Philip; Bowden, Nathaniel Sean

A scintillator system is disclosed for detecting incoming radiation. The system makes use of a scintillator structure having first and second dissimilar materials. The first dissimilar material emits a first color of light and the second dissimilar material emits a second color of light different from the first color of light. Either one, or both, of the first or second colors of light are emitted in response to receipt of the incoming radiation. A plurality of light detectors is disposed in proximity to the scintillator structure for detecting the first and second different colors of light and generating output signalsmore » « less

Non-contact monitoring of biofilms and corrosion on submerged surfaces with electrochemical impedance spectroscopy

Patent Turick, Charles E.; Milliken, Charles E.; Colon-Mercado, Hector; ...

Systems and methods for monitoring microorganisms on a surface are provided. In particular, a flat, patterned sensing electrode can be positioned proximate a surface in non-contact relationship with the surface. The sensing electrode can include a working electrode and a counter electrode. The surface and the sensing electrode can be submerged in an aqueous medium. An alternating current signal can be applied at the working electrode. The signal can propagate through the aqueous medium and can be measured at the counter electrode. The presence of microorganisms on the surface can cause changes in the signal as the signal propagates throughmore » « less
